// How it works

03

// Why this is different

Your PDF never leaves your machine.

Most online page-numbering tools upload your document to a remote server, stamp numbers on it there, and send back the result. Your file travels through systems you have no visibility into.

fwip works differently. The numbering engine runs entirely in your browser. Your PDF is read from your device, processed on your CPU, and the result is saved back to your device. No server is involved. We literally cannot see your file.

No server processing

Everything runs on your device using WebAssembly. Your file never touches a network.

No account required

Drop a file. Get a result. No sign-up, no email, no password.

No subscription

Free in the browser. $99 once for the offline bundle. That's it. Forever.

Works offline

The desktop version works with no internet connection at all.

// Questions

Frequently asked.

How do I add page numbers to a PDF without uploading it?▾
Drop your PDF onto fwip. The page numbers are stamped directly in your browser using pdf-lib. Your file never leaves your device and no server is involved.
Can I choose where page numbers appear on the page?▾
Yes. fwip lets you place numbers at bottom centre, bottom right, or top right. You can also choose from three font sizes and set a custom starting number.
Does adding page numbers change the PDF content?▾
Page numbers are embedded as text directly into each page. The original content is preserved. The resulting PDF works in every reader.
Is there a page limit for adding numbers to a PDF?▾
The browser version handles PDFs up to 200 MB with hundreds of pages. For larger files or batch processing, the offline bundle has no limit.
